[0/5] memblock tests: add tests for

Message

These patches add tests for memblock_alloc_exact_nid_raw(). There are two
sets of tests: range tests and NUMA tests. The range tests use a normal
(i.e., UMA) simulated physical memory and set the nid to NUMA_NO_NODE. The
NUMA tests use a simulated physical memory that is set up with multiple
NUMA nodes. Additionally, most of these tests set nid != NUMA_NO_NODE.

The range tests are very similar to the range tests for
memblock_alloc_try_nid_raw(). The NUMA tests have the same setup as the
corresponding test for memblock_alloc_try_nid_raw(), but several of the
memblock_alloc_exact_nid_raw() tests fail to allocate memory in setups
where the memblock_alloc_try_nid_raw() test would allocate memory. Also,
some memblock_alloc_exact_nid_raw() tests drop the lower limit of the
requested range in order to allocate within the requested node, but the
same setup in a memblock_alloc_try_nid_raw() test allocates within the
requested range.

Rebecca Mckeever (5):
